Nonsense syllable speech materials are often used when investigating speech perception in quiet
and under adverse conditions. The main advantage of using nonsense syllables over words and
sentences is that the acoustic as well as linguistic context is minimal. This paper describes the
considerations involved in producing three anechoic recordings of 14 male and 14 female native
talkers of Danish each speaking 65 nonsense syllables repeated three times with falling F0 (total of
16380 syllables).
